No. Refit all owner-accessible covers as the manual requires before operation. A cover left open after cleaning is not a normal airflow adjustment.
Understanding this situation
Covers can protect components and form part of the intended air route. Removing one to make the machine seem cooler or quieter changes the operating conditions without diagnosing the cause.
A useful next step
If a cover or latch will not refit, stop and obtain the correct guidance. Do not tape a damaged panel into an approximate position or run the dryer to see whether a warning clears. Explain any maintenance performed before the problem appeared.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
